Abstract
A magnetic sensor includes an MR element. The MR element includes a free layer. The free layer has a first surface having a shape that is long in one direction and a second surface located opposite the first surface, and has a thickness that is a dimension in a direction perpendicular to the first surface. The first surface has a first edge and a second edge located at both lateral ends of the first surface. In a given cross section, the thickness at the first edge is smaller than the thickness at a predetermined point on the first surface between the first edge and the second edge.
